why am i not getting achievments?

I been playing for achivemnts for a little bit and i should of gotten the all alone achivment i played on a defiant map and i was teh last person stading still didnt get achivment. twice today i played 1 flag CTF and the other team didnt even touch the flag both rounds and i still didnt get achivment and was also on a defiant map. whats going on?

Hmm, I went through your Game History and you definitely did get a Last Man Standing medal on Condemned, and played One Flag CTF on both Highlands and Condemned, so it’s not like you were playing the wrong gametype on the wrong map.

You should have gotten the All Alone achievement, and since I can’t see on the Game History for the One Flag CTF, I can’t verify if they did or didn’t touch the flag.

That’s really bizarre. I don’t know why you didn’t get them, as you should have!

My last achievements won’t register either. I tried doing it legit and then started boosting, but they wont show up. So, I think it’s an unfortunate glitch.
